RepRap Guru 3D Printer. Marlin sketch will not complie.

so i got a RepRap Guru pursa I3 V2. it requires you download the Marlin “software” into the arduino ide and compile it onto the arduino mega.

i open the sketch from the un zipped file exactly as it says to do in the instructional video. i hit compile and get the following errors. keep i mind i have made no changes or alterations.

i am so so sorry if i am not posting the error message propely. i read the beginners forum and hope i am doing it correctly.

Arduino: 1.8.1 (Windows 10), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

I downloaded the latest Marlin from github, here. Marlin compiled and uploaded, to my Mega2560 clone, with IDE1.8.5 Win10 with no errors (but a bunch of unused parameter warnings). The only thing that I can think of is that your Marlin installation is somehow corrupt. Where did you get the version of Marlin?

The RepRap forum for Marlin probably would be a good place to ask this question if you don't get help here.

dude your the man. im not sure if any of the info will help yet but atleast i have a place to start now. thanks for the help boss.
